i Application filed April 27, 1903. Serial No. 154,532. (No model.)

.To all whom it may concern.-

Be it known that I, J AMES ELLWooD J oNEs, a citizen ofthe United Statesof America, residing at Switchback, in the county of Mc- Dowell,in theState of. West Virginia, have invented certain new and usefulImprovements .4 in Machines for Discharging Coke-Ovens, of

which the following is a speciiicat'ion.

rlhis invention relates to a coke-puller designed to be operatedbymachine for pulling coke from coke-ovens, and it is particularly adaptedfor discharging coke from beehive coke-ovens. In the manufacture ofmetallurgical coke the oven known as the beehive-oven, so called becauseof its domeshaped form, has been generally adopted, being found to givethe best results. In the burning of thecoke the coke is produced in acaked mass, having a vertical stratification,

and it is desirable to avoid as much as possi# ble breakage of thesticks and lumps extracted from the oven.

Theinvention consists principally in a cokepuller having an underworkingor wedgeshaped scraper operating on the instroke into the oven to loosenthecoke for withdrawal and provided with adjust-able means operative onthe outstrok'e for grasping or holding loosened coke disposed over andabove Vthe scraper, wherebya thorough discharge of the oven may beobtained. t

The invention consists, further,in a cokepuller comprising anunderworking scraper operative on its instroke to loosen coke forWithdrawal and means in the form of an up- Wardly-swinging` plateconnected therewith and operative on the outstroke for holding theloosened coke over and above the scraper.

Figure l ofthe accompanying drawings repre'sents a side elevatiompartlyin section, on

` line 1.1 of Fig.3 of one embodiment of this mechanicalcokepuller inconnection with a coke-oven, a coke-car for receiving the coke i pulledfrom the oven, and a machine-car on which the pullerA is mounted,partsbeing broken out for convenience o f illustration.

Fig. 2 represents a transverse section on line 2 2 of Fig. 1.

Fig. 3 represents,on an enlarged scale, avertical transversesection online 3'3 of Fig. l. Fig. 4 represents, on an enlarged scale, a sideelevation of the coke puller proper, partly in section, on line 4 4 ofFig.

a part of the coke-puller and the coke-holding means in modified form.

The saine reference-numbers indicate the same parts in all the figures.

This coke-pulling apparatus may be used for discharging various forms ofcoke-ovens. The drawings represent fragments of a beehive coke-oven l0,provided, as usual, with atop opening, which serves for a feed and blastopening, and with a lateral dischargeopening l2. These openings areclosed and sealed in the usual manner during the coking operation or apart thereof. A number of such coke-ovens are arranged side by side, anda railway-track 2O is disposed in front thereof, on which travel thecoke-cars 30 for receiving and conveying away the coke drawn from theoven. Any other suitable means may be employed for disposing of the cokewithdrawn from the ovens. A track 40 is disposed outside the track 2Oparallel therewith,.and a machine-car 50, on which the dischargingapparatus is mounted, travels on said track 40. A suitable frame foroperating the mechanism of-the coke-puller proper is mounted on the car50. The frame shown for this purpose comprises two standards 51 and 52,secured to the platform of the car at opposite ends thereof. Thesestandards are connected by a top cross-bar 53 and provided,respectively, with horizontal shaft-bearings 5l and 55. '["he cross-bar53is provided with a vertical shaft-bearing 56, and the car-platform isprovided in line with the bearing 56 with a corresponding verticalshaft-bearing 57, having an exterior flange 58, adapted to serve as astepbearing. The platform of the machine-car is also provided withstandards, as 60, on one side and with standards 62 and 63 on the otherside thereof. The rst two of the standards above referred to areconnected by longitudinal rails 64; and 65, disposed parallel -with eachother in alhorizontal plane about midway of the height of the mainframe, and these rails form a guideway for the coke-puller,

as hereinafter described.

IOO

Corresponding rails 66 and 67 connect the standards 62 and 63 and form aguide at the other side for said coke-puller.

A horizontal driving-shaft 70 is supported in the bearings 54 and 55.This shaft is provided with a crank 71, a fly-wheel 72, andvalve-eccentrics 73 and 74. Any suitable means maybe employed forimparting motion to the driving-shaft-suoh, for inst-ance, as amotorcylinder 80, disposed on the platform 50, the piston rodv thereofplaying through a guide-bracket 82, attached to the frame, and beingconnected by a pitman 83 with the crank 71. This motor-cylinder isprovided with a valve-chest 84 for the inlet and exhaust of the steam,air, or other motive fluid. This engine may be provided with any meansusually employed for stopping, starting, and reversing, controlled, forinstance, by a reversinglever 85. Two bevelpinions and 91 are disposedloosely on the driving-shaft. The innet` ends of the sleeves of saidpinions are provided with clutch-faces of any suitable form. Aclutch-sleeve is splined on said driving-shaft 70 between said pinions,and the opposite ends thereof are provided with clutch-faces adapted toengage said pinions respectively. An actuating-le-v ver 9G, suitablypivoted on the frame, is provided with a forked inner end which engagessaid clutch-sleeve, whereby the latter may be shifted into and out ofengagement with either of said pinions for driving and reversing themechanism operated by the driving-shaft and out of engagement with bothsaid pinions for stopping said mechanism.

A vertical shaft is supported at its upper end in the shaft-bearing 5(3and at its lower end in the shaft-bearing 57. A bevel gear-wheel 101 isfixed on the upper end of the vertical shaft 100 and meshes with boththe bevel-pinions 90 and 91, loose on the driving-shaft 70. Thisvertical shaft is provided with two loose beveled pinions 102 and 103,disposed one above the other in reversed relation to each other, thesleeves or hubs thereof being provided with clutch-faces. Slidingclutches 104 and 105 are splined to the vertical shaft adjacent to saidpinions, respectively, and adapted to lock the said pinions to theshaft. A clutch-lever 106 actuates the clutch 104, and clutch-lever 107actuates the clutch 105.

A swiveling frame is mounted on the machinecar for carrying thecoke-puller, which is thrust into and retracted from the oven in pullingthe coke therefrom. This swiveling frame may be of any suitableconstruction. As herein shown, it comprises a sleeve 110, surroundingthe vertical shaft 100 and supported on the step-bearing 57. Threecurved arms or brackets 111, 112, and 113 extend upward from the upperend of said sleeve, the brackets 111 and 113 beingin the samediametrical plane and the intermediate bracket 112 being at right anglesto the others. The brackets 111 and 113 are provided at their upper endswith horizontal guideways '114 and 115,1espectively, through which thecokepuller bars work, as hereinafter described. The intermediate bracket112 is provided Withtwo horizontal shaft-bearings 120 and 130, disposedone above the other. Two stubshafts 121 and 131 are mounted'in thesebearings and project toward the vertical shaft 100. A pinion-sleeve 122is secured to the shaft 121 and provided with a straight pinion 123 andwith a beveled pinion 124, and a pinionsleeve 132 is secured to theshaft 131 and provided witn a straight pinion 133 and a beveled pinion134. The beveled pinion 124 meshes with the lower beveled pinion 102 ofthe vertical shaft, and the pinion 134 meshes with the upper beveledpinion 133 on said shaft, and motion is imparted to each of thestub-shafts in either direction by means of this gearing. The swivelingframe is oscillated by any suitable means. For this purpose it isshownas provided at the lower end of its sleeve with a worm-wheel 116, and ahorizontal shaft 117, having its bearings in the stationary frame of themachine-car, is provided with a Worm 118, engaging said worm-wheel,andwith an actuating-crank 119.

A coke-puller proper comprising a scraper adapted for loosening aportion of the caked coke on the instroke and having an adjustablecokeholder for grasping or holding the loosened coke over and above thescraper on the outstroke is mounted on and actuated from the swivelingframe. This coke-puller may be constructed in any suitable form whichadapt-s it for performing this double function. In the form ofembodiment shown in the drawings it comprises a shank-bar 140, a beveledscraper 150 at the outer end of said shank-bar, and a swinging plate160,l which in this showing constitutes a part of the cokelooseningscraper, a slide-bar 170, and a flexible connection 180 between theslide-bar and the swinging plate. The body of the scraper 150, which maybe solid or skeleton construction, is in the form of a wedge attached tothe bar 140 and beveled downward from its thick rear face 152 to itsthin front edge 151. The front edge is preferably arc-shaped to conformto the curvature of the oven-wall, and the rear faceis preferablystraight and at an abrupt angle to the inclined upper face. This body ispreferably provided on its under side with antifriction-rolls 153 and154,which travel on the oven-bottom. The shank-bar 140 is supported inthe guideways 114 and of the swiveling frame and also in the elongatedstationary guideway at opposite sides of the machine-car, whichlattervpermit the bar to swing horizontally to different angles as thesupporting-frame swivels. The in= ner portion of this bar is providedwith rackteeth 141, which engage the pinion 123, whereby said bar isreciprocated to thrust and re- IOO IOS

tract the scraper. This bar is provided in its outer portion at itsupper side with a guide 142, and on one side with stops 143 and 144.

The swinging plate 160, constituting the front face of the wedge-shapedscraper, is hinged at its upper edge to the angle of the scraper-body.This plate also extends ina transverse directiontol the bar 140 and hasa beveled outerIedge 161, adapted to the bonttom of theoven. This plateis provided on its upper face in line with -the shank-bar 140 with a lug162, to which vthe outer end of the bar 140 and is somewhat shorter thanthe lat` This slide-bar also moves through the chain 180 is connected.This lng is preferably thin and tapering to permit it to pass readilythrough the coke and su fticiently highA to afford leverage for theactnatingmeans. The pintle ofthe hinge of the swinging plate 160 isprovided with an antifriction-roll 164, over which` the chain passes.

' The slide-bar 170 is mounted on the shankter. guides of the swivelingand stationary frames heretofore mentioned and also at its outer endthrough the guide 142,attached to the bar This bar 170 is alsoprovidedalong its inner portion with rack-teeth 171, which are engagedbythe pinion 133, wherebymotion may be imparted to said barindependently ofthe motion of the bar 140. This slide-bar 170 isprovided with adependent lug 172, which plays between the stops 143 and144 of the bar 140, whereby the movementof the `sliding bar `170 islimited n The front end of the sliding bar is preferably beveled, so asto pass readily under the coke on the instroke.

'In Fig. 6 the swinging plate and actuatingbarare connected by the rod190 and the links 191 and 192, the link-191 resting on theantifriction-roller 164 when the swinging plate is closed, or nearly so.

The machine-car may be provided with suitable traction mechanismoperated b y the same power which operates the coke-puller.

This traction mechanism may consist of suitable transmitting-gearingbetween shaft 100 underneath the platform of the car and one of theaxles thereof and will pro'perly include devices for shifting it intoand out of gear, so as to move the car as desired.

In the use of this coke-drawing apparatus when the oven is ready tobedischarged the f n machine-@m and the receiving-car 30 are moved intoposition opposite the lateral ovenopening 12, the closure of which isremoved. The engine is started, and the driving-shaft moves in thedirection of the arrow 72 in lFig. 1.. The operator then by the lever 96shifts the clutchl 95 into engagementwith the pinion and by the lever106 shifts the clutch 104 into engagement with the pinion 102 on thevertical shaft 100. The cokepuller is thereby thrust into the oven, andthe scraper thereof moves over the bottom of the oven asuilicientdistance to make a proper drawing of the coke.

coke-puller the plate On this instroke of the 160, constituting thewedge to lift the coke above it beveled front face of the scraper, isin` lowered or closed position and operates as a from the caked mass ofcoke within the oven. At the end of the instroke the lever 106 isshifted so as to disconnect the pinion 102 from the shaft, and theinward movement of the coke-puller is stopped. Then the lever 96 islnoved to shift the clutch out of engagement with the pinion 90 vof thedriving-shaft and into engagement with the pinion 91 thereof, wherebythe motion of the vertical shaft 100 is reversed. Thenthe lever 107 isshifted into position to lock the clutch into engagement with thepinion` 103, and motion is imparted to the pinion 133, which engages thebar 170, whereby said' bar is retracted a distance equal to the spacebetween the stops 143 and 144 on the bar 140, and the swinging plate 160is lifted into raised position, as indicated in dotted lines in Fig. 1.This upward swing of the plate 160 lifts the mass of coke immediatelyabove said plate and thrusts it behind said plate and places the platein position to engage the depth of loosened coke above the body of thescraper on the outward stroke. The operator then shifts the lever 106and brings the clutch 104 into engagement with the pinion 102, wherebythe actuating-bar is retracted and the coke-puller withdrawn from theoven, with its plate in raised position, whereby substantially the wholemass of c'oke which was loosened on the instroke is discharged into thecoke-car 30. Then the levers 106 and 107 are shifted to throw both thegears 102 and 103 out of connection with the vertical shaft 100, wherebythe motion of the coke-puller is stopped. To make another stroke, thevertical shaft 100 is reversed either by reversing the engine or byshifting the clutch of therdriving-shaft. Then the upper bar is firstbrought into operative connection with said vertical shaft and is thrustforward, loosening the chain and permitting the plate 160 to fall intoclosed position. Then the lever 106 is actuatedto connect the bar 140with the transmitting mechanism, and the new thrust of the coke-pulleris effected as before. The first few strokes of the coke-puller arepreferably in a direct line at right angles to the tracks, it usuallyrequiring two or more drawings to remove the coke throughout a diameterof the cokeoven. After this is done lateral thrusts of the coke-pullerare made, iirst to one side and then to the other, the swiveling framebeing shifted for this purpose by the operator through the manipulationof the crankwheel 119.

' It will be understood that the separate driving-gearing for the bar140 may be omitted, if desired, and said bar operated through thedriving mechanism for bar 170 and its connection with the 'bar 140.Other details of construction may be varied without departing from thescopeof this invention.
